3 Claims.

This invention relates to supporting devices, and more particularly to a. supporting device for pumps of the vertical centrifugal type.

One object of the invention is to `enable the pump to be readily raised and lowered with respect to the liquid intended to be pumped.

Another object is to enable the pump to be expeditiously secured to or released from the supporting device.

Otherobjects will be in part obvious and in `part pointed out hereinafter.

In the drawing accompanying this specification and in -which similar reference numerals refer to similar parts,

Figure 1 is an elevation, partly` broken away,

of a supporting device constructed in accordance with the practice of the invention and a pumping mechanism secured to the supporting device,

Figure 2 is a transverse view taken through Figure 1 on the line 22,

Figure 3 isa side elevation of the supporting device, and V Figures 4 and 5 are perspective views of de-` tails of the invention.

Referring more particularly to the drawing, 2l designates a container for liquid 2| in which is submerged a pump 22 that is held in operative position by the supporting deviceA designated, in general, by 23.

The pump 22 is of the centrifugal type having a casing 24 and a cover 25 for the casing secured thereto by bolts 28. O n the upper side of the cover 23 is a tubular extension 21 that extends through an opening 28 in the upper wall 29 of the container 20 to support a driving motor 30.

The shaft 3| of the motor lies inthe extension 21 and is attached to an impeller 32 inthe casing 24 for pumping liquid 2| from the container vthrough a discharge conduit 33 extending, in the present instance, .through the opening 28.

The supporting device, constructed in accordance with the practice of the invention, comprises a plate 34 seated upon the wall 29. The plate is secured to the wall 29 by bolts 35 and has a radial slot 36 extending from the edge to the center thereof to receive the extension 21. On the upper surface of the plate is an arcuate lprojection 38, the inner surface of which is shaped to conform with the surface of the extension for which it constitutes a seating surface 39.

At the ends of the projection 38 are lugs 40 to interlockingly engage introverted hook portions 4| on the ends of a yoke member 42 that partly encircles the extension and, in the form of the invention shown, has a bolt 43 threaded through its apex to bear against the side of the extension 21 for pressing the extension nrmly against the seating surface 39. A nut 44 on the bolt 43 seats against the side of the yoke member to lock the bolt 43 in position.

To the end that the yoke member may be readily placed in the correct assembled position on the lugs said yoke is provided with a plate 45 that lies in the slot 36 and has shoulders 46 on its lower surface to lie upon shoulders 41 in the sides of the slot 36 for retaining the yoke member in correct relationship with the plate 34, and the elements with which the yoke interlocks.

An aperture 48 is preferably formed in the plate `34 to receive the discharge conduit 33.

In practice the pump 22 may first be inserted through the opening 28 into the container 20. The plate 34 is then disposed about the extension 21 and bolted to the wall 29. The yoke member is next placed in assembled position so that its hook portions 4| engage the lugs 40 and the plate 45 of the yoke rests upon the shoulders 41. The pump is then elevated to a desired p0- sition with respect to the liquid 2| or seated upon the bottom of the container, as illustrated in Figure 1, and the bolt 43 manipulated to clamp the extension 2l securely against the seating surface 39.

If, during operation of the pump, it may be desired to change its position it is merely necessary to unthread the bolt 43. The pumping mechanism may then be moved to the desired elevation and the bolt 43 again be tightened to secure the extension to the supporting device.

I claim:

1. A supporting device for a pump having an extension, comprising a plate having a seating surface for the extension and a radial slot leading from the intermediate portion to the edge of the plate to permit the passage of the extension therethrough to the seating surface, a yoke partly encircling the extension, means on the plate and the yoke interloekinglyengaging each other, and means on the yoke to clamp the extension against the seating surface and to secure the iirst mentioned means firmly together.

2. A supporting device for a pump having an extension, comprising a plate having a seating surface for the extension and a radial slot leading from the intermediate portion to the edge of the plate to permit the passage of the extension therethrough to the seating surface, projections on the plate on the opposite sides of the seating surface, a yoke partlyv encircling the the inner end of the slot for the extension, lugs l0 on the projection, a yoke partly encircling the extension and having hooks to interlockingly engage the lugs, means on the yoke to clamp the extension against the seating surface and to effect a rm engagement between the hooks and the projections, and a guide member on the yoke slidable in the slot to maintain the yoke in the correct clamping position.
